Methods for the In Vitro Characterization of Nanomedicines —Biological Component Interaction

An interesting article has been recently published, in the journal Personalized Medicine In the context of a public-private collaboration between Cristina Fornagera of Sagetis-Biotech and Conxita Solans, Scientific Director of Unit 12 of NANBIOSIS

This review summarizes the main techniques used to assess the interaction of nanomedicines with biological systems, highlighting their advantages and disadvantages. The translation of knowledge from novel designed nanosystems at a research laboratory scale to real human therapies is usually a limiting or even a final point due to the lack of systematic studies regarding two aspects: nanoparticle interaction with biological components and nanoparticle cytotoxicity.

A new versatile methodology to produce polymeric nanoparticles loaded with gold nanoparticles

Conxita Solans, Scientific Director of Unit 12 of NANBIOSIS together with researchers of her group, Colloidal and Interfacial Chemistry of CIBER-BBN and IQAC-CSIC and the Department of Pharmacy and Pharmaceutical Technology, University of BarcelonaIn have published the research paper “Versatile Methodology to Encapsulate Gold Nanoparticles in PLGA Nanoparticles Obtained by Nano-Emulsion Templating” in the journal Pharmaceutical Research. The scientists have shown that a novel and very versatile methodology has been developed for the production of polymeric nanoparticles loaded with gold nanoparticles.

In this work, gold-nanoparticles (AuNP) have been encapsulated in polymeric nanoparticles using a novel and versatile methodology based on nano-emulsion templating, which has allowed to encapsulate high concentrations of gold nanoparticles (> 100 pM).  Polymeric nanoparticles loaded with AuNP with sizes lower than 100 nm have been obtained using this methodology. In addition, a safe and easy methodology for the phase transfer of gold nanoparticles from aqueous to organic solvents has been developed. The biocompatibility of the designed nanoparticles with both cultured cells and erythrocytes has confirmed their suitability to be intravenously administered Therefore, these nanoparticles represent novel advanced imaging systems for biomedical applications.

New bioadhesive with 3D printing technique to improve pterygium surgery

Dr. José Luis Pedraz, head of Nanobiocel group and Scientific Director of Unit 10 of NANBIOSIS, participates in the public-private collaboration BIOTAPE project that will develop a new bioadhesive for its application in pterygium surgery to improve the currently used surgical techniques in the treatment of this eye disease that affects the conjunctiva and cornea.

The main cause of pterygium is the lack of lubrication of the eye by the tear film. This lack of lubrication may be due to various external factors such as excessive exposure to sunlight, harsh environmental conditions or even allergens, which causes dryness and subsequent irritation in that area. Pterygium grows in the form of fleshy mass on the cornea, being in these cases the application of surgery to extract it. So far the technique with better results is to place a graft of the conjunctiva of the eye itself in the place of removal of the pterygium, fixed by sutures or tissue adhesives.

In the BIOTAPE  project, 3D printing technique will be used to manufacture the new bioadhesive that will help reduce the current complications among which we can highlight the high rates of recurrence of the disease, surgical and post-surgical complications and the cosmetic result, not always satisfactory.

The new project, to be developed over the next three years, is funded with a budget of 513,000 euros by the Challenges-Collaboration program of the Ministry of Economy, Industry and Competitiveness and the participation of three Spanish companies (AJL OPHTALMIC, BRECA Health Care and Bilboftal-ICQO), the University of Miguel Hernández in Elche, CIBER-BBN and unit 10 of NANBIOSIS-ICTS.

NANBIOSIS by Pablo Laguna in CIBER-BBN Bulletin

Pablo Laguna, Scientific Director of Unit 27 of NANBIOSIS considers the added value offered by the ICTS NANBIOSIS in an interview at February 2017 CIBER-BBN Bulletin.

“The relevance of the ICTS NANBIOSIS is to make available to the entire scientific community of unique infrastructures that are shared and exploited in the most optimal way avoiding redundancies.” – Explains Pablo Laguna – “Having an incentive interaction mechanism, within the same centre, it has been addressed and are tackling challenges and projects with much greater depth, both in the excellence of the research, and in its possibilities of translation to the clinic and industry.”

Pablo Laguna Scientific Director of CIBER-BBN during 2011-2015, played an important role in the creation and impulse of NANBIOSIS, signing a scientific and technological cooperation agreement with Jesus Usón Minimally Invasive Surgery Center (JUMISC) in November 2011 that served as the basis for the creation of NANBIOSIS and its incorporation to the Map of Spanish ICTS (Singular Scientific Technological Infrastructures) in 2014.

New implants for the treatment of infections and bone tumours

Researchers of Unit 26 of NANBIOSIS participate in the design and evaluation of the cellular level of a new hybrid material for the creation of intelligent-scaffolds implants that open the door to a more efficient treatment of infections and bone tumors.

The main novelty is the incorporation of a mesoporous matrix of silicon, calcium and phosphorus oxides, with molecular gates that would allow the controlled release of substances stored inside the pores, such as antitumor drugs or antibiotics. A molecular gate is a mechanism whose opening depends on certain external stimuli, in this particular case the drugs would only be released in the presence of enzymes associated with a tumor or a infection in the bones.Nowadays there are scaffolds that allow the slow release of a drug, but this is produced automatically and non-specific.

Molecular gates have been characterized by the use of the Nuclear Magnetic Resonance Unit 26 of NANBIOSIS
